(Python) Adding Attributes to an XML Node

Demonstrates how to add attributes to existing XML nodes.

The input XML is this:

<abc>
    <xyz>
        <mmm>123</mmm>
    </xyz>
</abc>

The output XML is this:

<abc a="123">
    <xyz b="456">
        <mmm c="789" d="000">123</mmm>
    </xyz>
</abc>

import sys
import chilkat

xml = chilkat.CkXml()

success = xml.LoadXmlFile("add_attribute.xml")
if (success != True):
    print xml.lastErrorText()
    sys.exit()

#  Add an attribute  a="123" to the root node:
xml.AddAttribute("a","123")

#  Navigate to the 1st child.  After calling FirstChild2,
#  "xml" now references the node with the tag "xyz".
xml.FirstChild2()
xml.AddAttribute("b","456")

#  Navigate to xyz's first child, which is the node having the
#  tag "mmm".
xml.FirstChild2()
xml.AddAttribute("c","789")
xml.AddAttribute("d","000")

#  Revert back to the XML document root node
xml.GetRoot2()

#  Examine the result:
print xml.getXml()
